AXE WITH DETACHABLE BLADE Filed Jan. 3, 1946 Patented Mar. 7, 1950UNITED STATE 2,499,345 AX WITH DETACHABLE BLADE Epps Joseph Adams,Augusta, Ga. Application January 3, 1946, Serial No. 638,727

1 Claim. 1

My invention appertains to an axe construction in which the head intowhich the handle is inserted, and the blade are separable and preferablyof difierent material; that is, the head may be made of soft or cheapergrade of iron, while the blade is made of tool steel with an edge whichis suitable for taking a certain amount of hardening and grinding.

The following advantages of this construction should be noted.

The axe head into which the axe handle is attached in the usual mannershould practically last indefinitely, provided that a reasonable amountof care is used to protect it from rusting, bending or breaking.

The blade, made of costlier material, is very durable as regards wear,and keeps its edge and sharpness without regrinding for a considerabletime. Being of small size, as compared with the entire axe, it can bemanufactured cheaply.

When one blade has been worn out, the securing of a new blade to an oldhead, needing no fitting, as all parts would be standard, is equivalentto obtaining a brand new axe at a considerably reduced price.

Other advantages will occur from reading the following description withthe attached drawing.

One embodiment of the invention is illustrated on the drawing in which:

Figure 1 is a perspective view of the axe assembled with a portion ofthe handle.

Figure 2 is a section along line 2-2 of Figure 1.

Figure 3 is a side elevation of the axe-head alone.

Figure 4 is a vertical section along line 4-4 of Figure 3, slightlyenlarged.

Figure 5 is a side elevation of the axe-blade alone.

Figure 6 is a vertical section taken alon line 6-45 of Figure 5.

In the drawing, like reference numerals denote like details in thedifferent views.

The head of the axe is denoted by numeral l having a hole l2therethrough to accommodate a conventional axe-handle i I. At the lowerend of the head which is slightly more than half the length of anordinary axe, a blade i3 is firmly secured. When assembled together, thehead l0 and the blade l3 have a smooth taper from the fiat top 14 downto the sharp edge E of the blade I3. A mortice cut I6 is formed thereinby an inclined cut surface ll which slants from an undercut edge l8. onthe right side, as seen in Figure 2, down to a similar edge l9 on theleft 2 side of the axe. This mortice cut I6 tapers upwardly from thebottom edge 19 of the axe head to the top edge I8 thereof.

The blade 13 has a correspondingly tapered tongue 29 made to fit tightlyin the mortice cut [6 in the axe-head. After wedging in the blade [3firmly in the mortice IE it is additionally fastened by a transversescrew 2|, which is threaded as at 22 in the heavy middle part of theaxe. This screw 2| has preferably a beveled head which is countersunk asat 22 in the blade, which is not threaded.

After the head and blade are thus assembled, the side faces should beground and the edge l5 sharpened.

It is to be understood that the invention as here disclosed is notlimited to the details here described and shown but that the same may bevaried without departing from the spirit of the invention as defined bythe subjoined claim.

I claim:

An axe having a detachable blade and comprising a head having side facesand first and second end portions, a cut-out in one side face of thehead and at the second end of the head, said cut-out including aninclined bottom surface sloping from one side face of the head to theother side face of the head, said cut-out also including a pair of sidewalls diverging toward the second end of said head, the side walls ofsaid cut-out being dovetailed, said blade having a tongue, said tonguebeing wedge-shaped in two planes at right angles to each other, saidtongue fitting tightly in said cut-out and including a pair ofconverging dovetailed side edges contacting the side walls of saidcut-out.
